Abstract

The invention discloses a rope coating layer in the technical field of coating layers. The rope coating layer contains the following components in percentage by mass: 5%-20% of polyether 210, 3%-5% of isocyanate, 0-1% of dimethylolpropionic acid, 0-0.5% of trimethylolpropane, 0-2% of triethylamine, 1%-6% of acetone, 0-5% of an emulsifying agent, 5%-15% of butyl acrylate, 5%-10% of methyl acrylate, 0-3% of acrylic acid, 0-5% of methyl methacrylate, 10%-15% of a polytetrafluoroethylene emulsion, 5%-10% of an initiator and the balance of water. The rope coating layer has the beneficial effects that the formula compatibility is reasonable, and the process is rigorous; the performance of the product is improved, the rope coating layer is high in adhesive force, large in cohesion and stable in performance and has wear resistance, weather resistance, aging resistance and corrosion resistance, and the service life of a rope is greatly prolonged.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a rope coating and a preparation process thereof. Background technique [0002] With the development of our country's economy, the application of ropes is becoming more and more extensive, and the quality requirements for ropes are becoming more and more stringent, especially during the use of marine ropes, a large amount of sand will seep into them between the yarns , friction cutting ropes, long-term use of ropes, easy to damage, low life, in order to solve this problem, the prior art uses a coating to stick the yarn together to directly reduce the entry of sediment. The layer has poor wear resistance and weather resistance, is easily corroded by acid and alkali, has low adhesion and poor effect. Contents of the invention [0003] The purpose of the present invention is to provide a rope coating with strong permeability, high adhesion, high cohesion, stable performance, wea...
